From 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 16 Apr 2005 15:20:36 -0700 Subject: Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

When the receiption of n-th line + * ends, HS is lowered. + * + * To transmit data over DMA, 7146 needs changing state at + * port B VSYNC pin. Any changing of port B VSYNC will + * cause some DMA data transfer, with more or less packets loss. + * It depends on the phase and frequency of VSYNC and + * the way of 7146 is instructed to trigger on port B (defined + * in DD1_INIT register, 3rd nibble from the right valid + * numbers are 0-7, see datasheet) + * + * The correct triggering can minimize packet loss, + * dvbtraffic should give this stable bandwidths: + * 22k transponder = 33814 kbit/s + * 27.5k transponder = 38045 kbit/s + * by experiment it is found that the best results + * (stable bandwidths and almost no packet loss) + * are obtained using DD1_INIT triggering number 2 + * (Va at rising edge of VS Fa = HS x VS-failing forced toggle) + * and a VSYNC phase that occurs in the middle of DMA transfer + * (about byte 188*512=96256 in the DMA window). + * + * Phase of HS is still not clear to me how to control, + * It just happens to be so. It can be seen if one enables + * RPS_IRQ and print Event Counter 1 in vpeirq(). Every + * time RPS_INTERRUPT is called, the Event Counter 1 will + * increment. That's how the 7146 is programmed to do event + * counting in this budget-patch.c + * I *think* HPS setting has something to do with the phase + * of HS but I cant be 100% sure in that. + * + * hardware debug note: a working budget card (including budget patch) + * with vpeirq() interrupt setup in mode "0x90" (every 64K) will + * generate 3 interrupts per 25-Hz DMA frame of 2*188*512 bytes + * and that means 3*25=75 Hz of interrupt freqency, as seen by + * watch cat /proc/interrupts + * + * If this frequency is 3x lower (and data received in the DMA + * buffer don't start with 0x47, but in the middle of packets, + * whose lengths appear to be like 188 292 188 104 etc. + * this means VSYNC line is not connected in the hardware. + * (check soldering pcb and pins) + * The same behaviour of missing VSYNC can be duplicated on budget + * cards, by seting DD1_INIT trigger mode 7 in 3rd nibble. + */ +static int av7110_attach(struct saa7146_dev* dev, struct saa7146_pci_extension_data *pci_ext) +{ + const int length = TS_WIDTH * TS_HEIGHT;
